The mum-of-one looked radiant as she posed in further gorgeous pieces from the latest collection from the fashion store.

Despite wearing an array of kaftans for part of the shoot, she got to flaunt her toned and trim body in some of the new bikinis that are set to hit shops later this year. The fashion-conscious WAG is modelling the latest range for the clothing store after signing a £2million deal with them in June 2010.

Not an ounce of fat could be seen, despite the festive period only being one month ago, and it was clear she was enjoying her time soaking up the sun on the white sands in Miami as she was rarely seen without a smile on her face.

Coleen, 25, first turned heads in a stunning sheer, yellow kaftan with coloured print designs along the hem.

Teaming the outerwear with long, gold disc earrings, she wore a generous number of bangles on her wrist and her hair was pushed off her face.

It looked more like she was about to strut down a catwalk rather than bask in the sun.

Another shot saw her ooze sex appeal in a simple khaki bikini as she stood under shelter from the sun. The two-piece showed off her bronze tan beautifully, which is no doubt a result from the endless holidays she enjoyed last year.

Coleen later wore a white tea-style dress with yellow print on which she teamed with a beige Panama hat and a side-plait, proving covering up on the beach doesnât always mean you have to lose sex appeal.

She really seemed to be getting into the shoot, which has now spanned two days, as she was seen talking with the photographers and stylists about how to tackle each shot and appeared keen to give her opinion.

However, there was clearly a lot of waiting around involved during the day as Coleen was seen sneaking in a cheeky yawn at one point.

The Liverpudlian lass had the same hands-on approach the day before, when she wore another range of the fashion retailer’s designs, as she was seen scrutinising pictures of her before they were approved.

The second day of shooting was clearly more packed than the first day though as Coleen seemed to have many more outfit changes.

Other outfits included a yellow-and-white striped strapless swimming costume and a strapless red floor-length dress which could actually double-up as a dinner-date frock.

She had tweeted earlier in the day about the high winds while shooting, but luckily they didn’t seem to affect her hair which remained pristine throughout the day.

Luckily Coleen got to take lots of breaks, resting by palm trees as she chatted away to those working on the shoot as well.

No doubt she is missing her two-year-old son Kai who is at home with her footballer husband Wayne Rooney while she is on her working holiday.

Coleen has previously modelled clothing for Asda’s George range in a £3million deal from 2006 to 2008.
